N2 - Intraosseous (IO) needles are used to obtain vascular access in pediatric patients during emergent situations. Recent literature has raised concern about high rates of IO malposition in younger children. Despite the widespread use of IO access in the pediatric population, there is scarce evidence regarding the ideal needle length or optimal access site. This study uses a radiographic approach to determine the appropriate IO needle length and access site to minimize the risk of malposition in children younger than 2 years. Radiographs of the lower extremities were obtained from the electronic database from a single tertiary care center. Using lateral views, anteroposterior measurements were obtained at 2 axial planes, located 1 cm superior to distal femur physis and 1 cm inferior to distal tibia physis. Based on the measurements, we calculated the probable needle tip positions if the needle was placed to the hub at the skin level using the EZ-IO (Teleflex Ltd, Wayne, PA) preset needle sizes. For subjects younger than 6 months, the 25-mm needle minimized malposition in the femur site with a 45.7% appropriate position rate, and the 15-mm needle minimized malposition in the tibia site with a 57.1% appropriate position rate. For the older age groups, we did not find a standard needle that would consistently minimize malposition in the femur site. For the tibia site, the 25-mm needle minimized malposition risk, with appropriate position rates of 81.0%, 87.5%, and 91.1% in the 6- to 12-month, 13- to 18-month, and 19- to 24-month groups, respectively.
